IMPROVEMENT IN DEVICES FOR OPERATING SAFE-DOORS.

Specification forming part of Letters Patent No. 145,032, dated November 25, 1873; application filed July 1o, 1873.

. To all whom fit may concern:

Be it known that I, HIRAM B. TRIPP, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Safes, of which the follo wing is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification.

The present invention relates to the hanging of safe-doors, more especially such doors as are constructed with a right-angular tongueand-groove joint between the door and its jamb, and the purpose of the invention is to secure a movement of the door out from its jamb in'a straight line, or nearly so, sufficient that when the door is swung it will perfectly clear the edges, grooves, and tongues of the j amb.

The invention consists, first, in combination with said doors, of a hinge constructed of two leaves pivoted together, with the one fastened to the door, and the other pivoted to abracket or third leaf fixed to the outside of the safebody or frame in which the door swings, and of a rod arranged to turn in suitable bearings of the door, entering the free leaf of hinge on door, and constructed together with said free leaf, as, when it (the rod) is turned in the one direction, to draw the door at such portion out of its jamb, and when turned in the other direction, to move it into its jamb, the door when moved out, as stated, if opened, swinging through the free leaf of hinge on the bracket-leaf referred to as on safebody or door-frame; second, in combination with a hanging of the door, substantially as above described, or any equivalent therefor, of a spindle arranged to turn within the safe-door, -When said spindle is connected to the operating-rod, or equivalent thereof, in said hinging, in such manner as, by turning said spindle, the said operating-rod will be actuated in either direction to produce the desired and proper moving out and in of the door with regard to its jamb; third, in combination with a hanging of the door, substantially as described, of a spindle for throwing the bolts of the door, when said spindle is connected to the operating-rod, or equivalent therefor, in said hinge, in such manner that, by the turning of said spindle, the bolts will be thrown and the as the case may be, and in a said operating-rod actuated, the rst occurring before the door is swung out of its jamb, if the safe is to be opened, and after the door is swung into its jamb if the safe is to be closed.

ln the accompanying plate of drawings my improvements in safes are illustrated, Figure' l being an exterior elevation of a safe, showing its door as hung according to the several features thereof; Fig. 2, a horizontal section in plane of linex x, Fig. l; Fig. 3, atransverse vertical section in plane of line y y, Fig. l; Fig. 4, a view of the inner face of door, but on a reduced scale.

A in the drawings represents the body of a safe, to which B is the door, and C the jamb of the door, both constructed around their contiguous edges, if closed, with right-angular tongues and grooves, as shown in Figs. 2 and 3 O2, two hinges byfwhich door B is hung in safe-body A. The hinges C2V are similarly constructed, and are each formed of three parts in leaves c, b, and c. The parts or leaves ot and b are pivoted end to end at d, and the other end of part b pivoted to the part c. The leaf a is firmly secured by screws f, or otherwise, to the door, leaving the leaf b free thereof, and the leaf c is fixed to the safe-body A, or frame in whichthe door is hung. The hinge-pointof the leaf b and leaf c is such that, when the door is within its jamb, the leaf b will be at an acute angle horizontally from end to end in the face of the door. The hinges O2, constructed as above described, are arranged in horizontal positions upon the door, one above and parallel with the other, the door being adapted to swing horizontally open. D is a rod, arranged vertically upon the door B, and adapted to turn in fixed bearing-blocks E thereon. This rod D, at each end, enters an elongated recess, h, of the free leaf b to hinges O2, and at such portions of its length either more or less within the leaf b aforesaid it is constructed with cam or eccentric l. The rod D is the operating-rod, so called,'for the hanging, above described, of the door, and, by turning it around within. its bearings E, either more or less, it is obvious, with a proper amount of eccentric or cam periphery l, the door to which the hinges G2 are api plied will be moved out of or into its jamb, straight line,

or nearly so. `W ith a sufficient length of movement to the door, from the operation of the rod D above described, it is manif'est the door can be brought out of its jamb sufficient for the tongues and grooves of its edge to clear those of the jamb, when the door may be swung open. The door, in swinging open, turns by the leaves b on the pintle attached to leaves or brackets o. m, a pinion-wheel secured to operating-rod D, in the present instance near the lower hinge of door to safebody; n, a rack-bar arranged to interlock with pinionwheel m, and slide in a groove formed in the safe-body A and door B. rlhis rack-ba n' is continued along the front face of the safedoor B, resting upon a guide-bracket, p, fixed to safe-door, where, by its rack q, it is arranged to engage with a sector-tooth wheel, r, fastened to or forming a part of a spindle, E2, arranged to turn within the door B, said spindle E2 having handle F, for convenience in turning it.

Vith a connection of parts between spindle E2 and operating-rod D, substantiall5T as above described, it is obvious turning said spindle actuates the rod D, which, consequently, through its movement within the leaves b of hinges C2, moves the door out of or into its jamb, as the ease may be, and in the manner before described. i

The spindle E2, in the present instance, is the spindle for throwing the bolts F2 to safedoor B, said bolts F2 being arranged substan tially in the same manner as ordinarilythat is, to move horizontally across the inner face of door through vertical guide-bars Gr fixed thereto, and to interlock within the door-jamb. For the spindle *l2 to throw the bolts F2, its end upon the inner side of safedoor is provided with a sector gear-wheel, s, to engage with a horizontal toothed rack-bar, t, iiXed to the rail O, tying together the two bolts F2 of the safe-door.

With the gear-wheel s of spindle E2 in connection with the rack-bar t of tie-rail O forbolts F2, it is obvious the bolts can be thrown either in or out by simply turning the spindle around in the one or the other direction, as may be required.

With sector gear-wheels 1' and s on spindle E2, and their proper relative adjustment on spindle, it is plainly obvious that the movement of the bolts F2 in the unbolting of the safe may be made to fully take place before the movement of the door out of its jamb commences, and vice versa-that is, the one oper ation following the completion of the other-- it being obvious that if the spindle E2 is employed to perform both operations, above de scribed, sector gear wheels or equivalents therefor must be used, and they must be relatively arranged therefor on the spindle, such arrangement being shown in the drawings.

In lieu of toothed gearing being employed for a connection -between spindle E2 and operating-rod D, and also between spindle and door-bolts, frictional gearing or other suitable mechanical means-such as, for instance, crank-arms and pitman-rods-may be used 5 but an arrangement of parts, as a whole, substantially as above described, is most desirable and eiiicient.

L, a stop secured to safe-door in position to limit and arrest the movement of the extension rack-bar, and on the door in its line or direction of move-ment, to move the door out of its jamb.

The actuating of door-hanging by the turning of a spindle, E2, may be applied to other forms of hanging than that herein particularly described, and therefore it is not intended to limit such feature of this invention to any parA tieular door-hanging so long` as it is susceptible of adaptation for operation by the spindle.

Having thus described my improvements in safes, what I claim, and desire to secure by Letters Patent, is-

l. A safe-door hinge, C2, consisting of the leaves c I) c, connected together and applied to said door and safe-body as herein described, in combination with the rod D, having cams or eecentries Z Z and a spindle arranged to turn within the door and connected with rod D, as herein described, for the purpose set forth.

2. The combination, with a door hung substantially z s herein described, of a spindle arranged to turn within the door, when such spindle is connected to the rod or other part for operating said door-han ging, substantially as and for the purpose described.

3. rlhe combination, with a door hung substantially as herein described, of a spindle arranged to turn within the door, when such spindle is adapted to both actuate the rod l) or its equivalent, for operating' said doorhang ing, and to throw the bolts on the door, substantially as described. Y

The above specification of my improvements in safes signed by me this 14th day of June, .1871.
